Roof Fan

The Farm Electronics roof fan is designed to provide efficient roof space ventilation and air movement for the minimum installation and running cost. The long case design increases the directional “throw” of the air to ensure the maximum effect in roof space. It is available with single or multi-starter control panels for manual or automatic operation.

Fandangler Bracket

The manual or motorised fandangler bracket enables the fan to be turned and directed easily and quickly to ensure maximum efficiency in operation.

The fan is suspended by chains from a sturdy box section crossbar. Direction of ventilation is set by rotating the crossbar manually against a friction washer, which holds the fan in the desired position.

The motorised fandangler bracket provides continuous movement of the fan through a 90-degree arc to spread and improve the air distribution over a wide area. A tiny-geared motor then moves the fan slowly backwards and forwards through a 90-degree arc whenever the fan is running.

A dedicated electrical isolator fuse/switch is provided with the unit to feed power from the normal fan supply to the fandangler motor.
